[rrd-users] Re: Changing line color

[Serge Maandag]

The over line will be drawn exactly on top of the under line, so there
is no need to hide parts of the under line.
Try:

DEF:in=my.rrd:In:AVERAGE 
CDEF:over=in,34000,GT,in,UNKN,IF 
LINE2:in#00ff00 
LINE2:over#ff0000

Subject: [rrd-users] Changing line color



I have figured out from the tutorials and examples how to do changing
colors
based on thresholds on AREA graphs.

Is it possible to do changing colors on LINE? graphs?  The AREA trick
doesn't work on line graphs because the lines aren't connected, this is
especially noticeable on low resolution graphs.  For example I tried
this

DEF:in=my.rrd:In:AVERAGE 
CDEF:under=in,34000,LT,in,UNKN,IF 
CDEF:over=in,34000,GT,in,34000,-,UNKN,IF 
LINE2:under#00ff00 
STACK:over#ff0000

And here is what it looks like: http://miguel.vargas.com/test.png.


Is there a way of doing this?
